The endless conveyor can include a first end and a second end opposite thereto in which the second end is positioned in the third aperture on the apron. Moreover, a chute can be positioned within the dump body that meters material from the dump body to the second end and third aperture for dispensing out of the dump body. The chute can be controlled by an air cylinder system, for example. In another example, the chute can be controlled by a hydraulic, cylinder, electrical, motor, combustion engine, among others.

The vehicle can further include a spreader that is coupled to the frame of the vehicle. In particular, the spreader is not coupled to the dump body. One or more guides can be coupled to the endless conveyor to direct or guide material exiting the second aperture.

With reference to the drawings, like reference numerals designate identical or corresponding parts throughout the several views. However, the inclusion of like elements in different views does not mean a given embodiment necessarily includes such elements or that all embodiments of the invention include such elements.

Referring now to FIGS. 1 and 2, a vehicle, such as a dump truck, is illustrated by reference numeral 10. The vehicle 10 includes a frame 12, an engine supported by the frame 12, a cabin 14 supported by the frame 12, a front axle and at least one rear axle 16 supported by the frame 12, and a dump body 18 supported by the frame 12. The dump body 18 is movable relative to the frame 12 between a dump position (also referred to as inclined position or raised position) for dumping material shown in FIGS. 2 and 3 and a load position (also referred to as horizontal position or lowered position) relative to the ground shown in FIG. 1 by one or more hydraulic cylinders 20 attached to the frame 12 and to the dump body 18 at bracket 22 in any suitable manner, such as by bolts 24.

Turning now to FIGS. 3-28 in addition to FIG. 1, the dump body 18 includes first and second sidewalls (e.g., driver side and passenger side sidewalls) 40 and 42, a front wall 44, a floor 46 having a first opening or aperture 48, a tailgate 50 having a second opening or aperture 52, and an apron 54 below the tailgate 50 having a third opening or aperture 56. The second and third openings 52 and 56 are substantially perpendicular to the first opening 48.

As shown in FIG. 4, to support and strengthen the opening 48 in the floor 46, the dump body 18 includes a conveyor support assembly 60, which is shown in an exploded view in FIG. 4 along with the apron 54. The support assembly 60 includes a conveyor front plate 62, a pair of angle iron portions 64, a body hinge plate 66, and a conveyor guide 68. The conveyor front plate 62, which is an L-shaped plate, is secured below the floor 46 near a first end 70 of the opening 48 proximate the front wall 44. The pair of angle iron portions 64 extend the length of the opening 48 and are secured to a pair of sills 72 and 74 (also referred to as the pair of long sills 72 and 74). The long sills 72 and 74 extend longitudinally on either side of the opening 48 below the floor 46 and form with the iron portions 64 a track for wheel assemblies of an endless conveyor as discussed below. In an embodiment, the long sills 72 and 74 reside in the same plane as the third opening 56. The body hinge plate 66 is secured to the pair of long sills 72 and 74 near a second end 76 of the opening 48 proximate the tailgate 50 and below the pair of angle iron portions 64. The conveyor guide 68, shown as a u-shaped member, surrounds three sides of the opening 48 and is secured to the floor 46, such as by welding, such as by spot welding at openings 78. The conveyor guide 68 has a top portion 80 secured to the floor 46 and a side portion 82 that extends through the opening 48. The side portion 82 includes a plurality of openings 84 for securing a rubber strip to the side portion, such as by bolts.

The conveyor support assembly 60 supports and/or guides the endless conveyor 100, shown in FIGS. 5-10. The endless conveyor 100 includes a first end 102 proximate the front wall 44 and a second end 104 opposite thereto proximate the third opening 56 in the apron 54. The endless conveyor 100 is installed in the dump body 18 by inserting the first end 102 into the third opening 56 and advancing the conveyor until the first end 102 is positioned near the first end 70 of the first opening 48 below the opening 48. The endless conveyor 100 is then coupled to dump body 18, and in the illustrated embodiment to the apron 54 via a pair of brackets 106 on opposite sides of the endless conveyor 100 that receive respective fasteners 108, such as bolts secured to the apron 54. The endless conveyor 100 can then be connected to a motor 110, such as a hydraulic direct drive motor connected to the dump body 18 that power the endless conveyor. In another embodiment, the endless conveyor 100 can have an integrated power source (e.g., motor, battery, etc.) in which the dump body is configured to mate. By way of example and not limitation, the endless conveyor 100 can include a power source on the second end 104 that is positioned in a cutout of one of the pair of long sills 72 and 74.

The endless conveyor 100 includes an endless belt 112, a plurality of longitudinally spaced slats 114 on the belt 112, and a pair of support rails 116 extending longitudinally along the sides of the endless conveyor 100. Material sits on the belt between the longitudinally spaced slats 114 and is directed towards the third opening 56 when the conveyor is activated. The support rails 116 can be any suitable shaped, such as c-shaped rails having portions along the sides, top, and bottom of the conveyor. Attached to the support rails 116 are a plurality of wheel assemblies 118 longitudinally spaced along the support rails 116. Each wheel assembly includes a vertical alignment plate 120, a wheel 122, an axle 124, which may be a bolt, such as a hex bolt extending through the wheel 122 and an opening 126 in the alignment plate 120, and a pair of nuts 128, such as hex nuts secured to each end of the axle to secure the wheel 122 to the alignment plate 120. During installation of the endless conveyor 100, the wheels ride along the track formed by the long sills 72 and 74 and the iron portions 64, and can rest against the track when the endless conveyor 100 is installed and/or secured to the dump body 18 for the winter mode.

The endless conveyor 100 directs the material to the third opening 56 where the material passes through a chute 130 shown in FIGS. 11-14. The chute 130 can be configured to meter material housed by the dump body 18 and includes a gate housing 132, a pair of guide strips 134, a pair of gate keepers 136, a pair of rods 138, and a gate 140. The gate housing 132 is formed by a piece of metal bent to include a planar portion 142 and side portions 144 extending from the planar portion 142. It will be appreciated that the gate housing 132 could alternatively be formed by a plurality of pieces coupled together. The guide strips 134 abut the planar portion 142 and the gate keepers 136 abut the guide strips 134 to form an area that guides movement of the gate 140. The gate keepers 136 and guide strips 134 have openings that align with one another and with respective openings in the planar portion 142 to receive fasteners 146 to secure the guide strips 134 and gate keepers 136 to the planar portion 142. The rods 138 extend between and are coupled to the side portions 144.

When the chute 130 is positioned in the dump body, bottom portions 148 of the planar portion 142 and the bottoms of the side portions 144 rest on the conveyor guide 68, and the side portions 144 have a profile that matches a profile of the tailgate 50, in particular to an inner portion of the tailgate 50. The side portions 144 are also angled so as to prevent damage to the side portions when the tailgate 50 is opened and/or closed. In particular, when the tailgate 50 is unlatched (e.g., via the air cylinder system for latching or unlatching the tailgate 50), the tailgate 50 can swing from 90 degrees to approximately 180 degrees with a hinge on the topside of the tailgate 50, wherein the swing motion can be toward the front of the vehicle or the rear of the vehicle). The chute 130 is then secured to the tailgate, for example by pins. The planar portion 142 is attached to an air cylinder system (discussed in more detail in FIG. 3) that is received in the second opening 52 in the tailgate 50. An arm of the air cylinder system is attached to one of a plurality of pieces of tubing 150 secured to the gate 140 to vary the metering of the gate 140 and control the metering of material dispensed via the endless conveyor 100.

The chute 130 is shown in the closed position in FIG. 11, where material is prevented from passing from the endless conveyor 100 through the third opening 56. The chute 130 is shown in the open position in FIGS. 5 and 6, where the chute 130 has moved vertically towards the top of the tailgate 150 and material can pass from the endless conveyor 100 through the third opening 56.

The material passing through the chute 130 and the third opening 56 is guided by material guides 160 shown in FIGS. 5 and 6. The material guides 160 are provided at opposite sides of the endless conveyor 100 to direct the material towards a spreader assembly 180. In another embodiment, the material guides 160 are replaced by a conveyor lip 162 shown in FIGS. 15-17 for directing material towards the spreader assembly 180. The conveyor lip 162 includes a body 164 having a curved portion, wings 166 extending from either side of the body 164, and attachment portions 168 having openings 170 for receiving fasteners for coupling the conveyor lip 162 to the dump body 118. In another embodiment, the conveyor lip 162 can be coupled to the endless conveyor 100.

The material passing by the material guides 160 or conveyor lip 162 is directed downward (via gravity after reaching the end of the endless conveyor 100) to the spreader assembly 180 shown in FIGS. 3 and 6, disposed below the endless conveyor 100 and attached to the frame 12 such that the spreader assembly 180 remains substantially parallel to the frame 12 when the dump body 18 is in the load positon and/or the dump position. For example, the spreader assembly 180 is stationary when the body and/or the conveyor 100 move between the load position and the dump position. The spreader assembly 180 includes a housing 182 defining an opening 184, a spinner 186 disposed in the opening 184, a plurality of angled plates 188 around a top portion of the housing 182 for directing the material towards the spinner 186, and a pair of connection rods 190 attached to the housing 182 that removably connect to respective receivers 192 attached to the frame 12. The spinner 186 is connected to the housing 182 in any suitable manner that allows the spinner 186 to spin relative to the housing 182. The spinner 186 is powered by a motor connected to the housing 182 or the frame 12, and the spinner 186 includes a plurality of circumferentially spaced vanes 194 on its upper surface. In another embodiment, the spinner 186 can be powered by a stand-alone power supply, an integrated power supply, a power supply used by the vehicle or a component of the vehicle, or a combination thereof,

Referring back to FIGS. 3 and 4 and the tailgate 50 in detail, the tailgate 50 is pivotally coupled to the first and second sidewalls 40 and 42 in any suitable manner, such as by pivot arms 200 and 202 received between respective brackets assemblies 204 and 206 at the tops of the first and second sidewalls 40 and 42 and secured by pins or other suitable coupler. The bottom of the tailgate 50 is removably held to the first and second sidewalls 40 and 42 by respective latches 210 and 212 that hold arms 214 projecting out from opposite sides of the bottom of the tailgate 50 in a lock position. The latches 210 and 212 can be moved to an unlock position to release the arms that allow the tailgate 50 to pivot. For example, the latch 210 can be moved by a first air cylinder system and the latch 212 can be moved by a second air cylinder system 216 shown in FIG. 18. By way of example and not limitation, the first air cylinder system can be positioned on a driver side of the vehicle, in a storage compartment within a driver side rear portion of the dump body 18, on a passenger side of the vehicle, coupled to a bottom portion of the dump body 18, in a storage compartment within a passenger side rear portion of the dump body, or a combination thereof. By way of example and not limitation, the second air cylinder system 216 can be positioned on a driver side of the vehicle, coupled to a bottom portion of the dump body 18, in a storage compartment within a driver side rear portion of the dump body 18, on a passenger side of the vehicle, in a storage compartment within a passenger side rear portion of the dump body, or a combination thereof. In an embodiment, the first air cylinder system can be substantially the same as and positioned in a similar spot as the second air cylinder system 216.

Each air cylinder system has one end coupled to a rear cylinder bracket 220 attached to the apron 54 and another end coupled to a respective linkage assembly 222, 224 connected to dump body 18 and the respective latch 210, 212. The air cylinder systems can be controlled from, for example, within the cabin 14 of the vehicle 10, for example by a switch or wireless control signal(s).

A third air cylinder system 230 can be provided that is received in the second opening 52 and positioned within an interior of the tailgate 50. The air cylinder system 230 can be positioned, for example in a center or substantially the center of the tailgate 50 and does not require a cross-bar or support that extends the width of the tailgate 50. For example, support brackets can be secured to an exterior of the tailgate 50 to which the third air cylinder system 230 can be removably coupled thereto. For instance, one or more lock pins can be used to secure the third air cylinder system 230 to the support brackets on the exterior of the tailgate 50. The third air cylinder system 230 is connected to the chute 130 as discussed above. The air cylinder system 230 controls movement of the metering gate 140 to allow/prevent access to the third opening 56, thereby controlling the flow of material onto a road or ground. The third air cylinder system 230 can be controlled from, for example, within the cabin 14 of the vehicle, for example by a switch or wireless signal(s) connected to the air cylinder system by the line 232.

The third air cylinder system 230 or an additional air cylinder system can also move the metering gate 140 prior to the tailgate 50 being released by the first and second air cylinder systems to prevent damage to the metering gate 140. For example, an air cylinder control system can utilize a lock mechanism that provides automated locking and unlocking of the tailgate 50 to allow/restrict pivotable movement of the tailgate 50 without damaging the air cylinder system 230, the chute 130, or control components of the air cylinder system 230. In particular, the lock mechanism can restrict unlocking the tailgate 50 or movement of the tailgate 50 until the chute 130 is moved to a position that allows for safe movement of the tailgate 50 without damaging the air cylinder system 230 or chute 130. For instance, the lock mechanism can maintain the locking of the tailgate 50 until the chute 130 and/or the metering gate 140 is moved to an open position so as to not be damaged with movement of the tailgate 50 since the chute and/or the metering gate 140 are coupled to the inside of the tailgate 50. Similarly, the lock mechanism can unlock the tailgate 50 when the chute 130 and/or the metering gate 140 is at an open position.

In an embodiment, the air cylinder system can be coupled or mounted to four brackets that are positioned on the exterior of the tailgate. In an embodiment, the air cylinder system can be positioned on an interior of the dump bed and, in particular, an interior of the tailgate 50. Additionally, control components of the air cylinder system can be housed in a compartment of a driver side rear corner (e.g., behind a taillight) or passenger side rear corner (e.g., behind a taillight) of the dump body 18, wherein the compartment is covered by a plate or access cover. In an embodiment, the air cylinder system can be mounted to brackets on an exterior of the tailgate 50 and the air cylinder system placed within an opening on the tailgate 50 inside the dump body 18 so the air cylinder system is positioned within the dump body proximate to the interior of the tailgate 50. It will be appreciated that the vehicle could be adapted to utilize one or more air cylinders or systems to control movement of the chute 130 or the tailgate 50.

Referring again to FIG. 4 and the apron 54 in detail, the apron 54 includes an apron skirt 250, apron reinforcement tubing 252 secured to a bottom of the apron skirt 250, a motor cutout flange 254, a pair of side plates 256 and 258 attached to ends of the apron skirt 250, a reinforcement member 260 between the side plate 256 and long sill 72, and a pair of cylinder brackets 220 attached to opposite sides of the apron skirt 250 for attaching to one of the first or second air cylinder systems.

The apron skirt 250 includes the third opening 56, which includes a first portion 262 and a second portion 264. The first portion 262 receives the endless conveyor 100 and is the exit area for material delivered by the endless conveyor 100 to the spreader assembly 180. The second portion 264 is reinforced by the motor cutout flange 254 and is provided for receiving the motor 110 (illustrated in more detail in FIG. 6) that can power the endless conveyor 100. By way of example and not limitation, the motor 110 can be a hydraulic direct drive motor and can be disposed in a cutout 266 of the long sill 72, the long sill 72, or a combination thereof.

Turning now to FIGS. 29-32, the vehicle 10 can include one or more pre-wet tanks, and in the illustrated embodiment first and second pre-wet tanks 270 and 272 that are removably coupled to the front wall 44 of the dump body 18. In an embodiment, the pre-wet tanks 270 and 272 are supported by a platform coupled to the exterior of the front wall of the dump body 18, wherein the platform is substantially parallel to the ground when the dump body 18 is in the load position. The pre-wet-tanks 270 and 272 can be supported by the platform and secured for additional stability to the dump body 18. For instance, the pre-wet tanks 270 and 272 can be coupled to the dump body 18 with one or more straps 274. The pre-wet tanks 272 and 274 can be positioned on an exterior wall of the front wall 44 with connections (e.g., plumbing, electrical connections, mechanical connections, etc.) running to a nozzle 276 (FIG. 5), such as a brass nozzle controlled by an operator, for example by a switch or wireless signal(s) in the cabin 214 of the vehicle. The nozzle 276 sprays a liquid, such as a deicing solution, onto the material passing through the spreader assembly 180. The liquid from the nozzle 276 can be guided towards the spinner by the angle plates 188. As shown in FIG. 2, the pre-wet tanks each include a first opening 280, 282, connected to the other by a hose 284 with shut-off valves 286 and 288 at each end, and a second opening 290, 292 connected to the nozzle by a respective hose 294 having a respective shut-off valve 296, 298.

The liquid is pumped from the pre-wet tanks 272 and 274 to the nozzle 276 by a pump/motor disposed in a compartment of the dump body 18. By way of example and not limitation, the compartment can be at the rear of the driver side sidewall 40 or the rear of the passenger side sidewall 42 along with respective wiring harnesses or wireless components for connectivity to the cabin 14. The compartment is covered by a removable cover 300 (shown in more detail in FIG. 19). A similar compartment and cover 302 (shown in more detail in FIG. 20) can be provided on the passenger side sidewall 42 for housing the pump/motor and/or a lighting harness or other suitable component.

Turning now to FIGS. 33-35, the vehicle 10 is shown in a summer mode where the dump body 18 can be used for hauling and dumping material. To convert the vehicle to the summer mode from the described winter mode above, the endless conveyor 100, the spreader assembly 180, the chute 130, the third cylinder assembly 230, among others can be removed from the vehicle 10. The endless conveyor 100 is removed by removing the bolts 108 and pulling the endless conveyor 100 out of the third opening 56.

In the specification and claims, reference will be made to a number of terms that have the following meanings. The singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. Approximating language, as used herein throughout the specification and claims, may be applied to modify a quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term such as “about” is not to be limited to the precise value specified. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Moreover, unless specifically stated otherwise, a use of the terms “first,” “second,” etc., do not denote an order or importance, but rather the terms “first,” “second,” etc., are used to distinguish one element from another.

As used herein, the terms “may” and “may be” indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of “may” and “may be” indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances an event or capacity can be expected, while in other circumstances the event or capacity cannot occur—this distinction is captured by the terms “may” and “may be.”

This written description uses examples to disclose the subject matter, including the best mode, and also to enable one of ordinary skill in the art to practice the invention, including making and using a devices or systems and performing incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to one of ordinary skill in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differentiate from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
